# Ocean Waves+ Calculator v1

Price: £55.00 (£55.00 Inc. VAT)

## Subject

Resistance to water particle acceleration and velocity induces forces due to drag and added mass on an immersed structural body - e.g. a wall, brace, transom, pile, etc. - which may be applied at any depth, inclination, orientation and/or buried/anchored in the seabed.
The best known theory for this conversion was developed by Morison, which is based upon drag and added mass coefficients, and is used to calculate the forces in this calculator.

## Calculator

You may calculate these forces independently from the water particle velocities and accelerations using our Waves calculator, or directly using this calculator, which identifies the force profiles through the wave and through the water column.
The data matrix generated in Waves+ may be post processed in a suitable spredsheet to identify the stresses and deflections in the structural body.
This calculator is not designated as a supplement to the Waves calculator, but as an alternative. If you don't need to calculate forces, Waves will suffice.
